1.服务器版本 CentOS 7.5
2.VirtualBox配置网络为桥接模式
3.物理机(宿主机)信息
-
ip:192.168.0.104
-
subnet mask:255.255.255.0
-
gateway:192.168.0.1
4.查看服务器ip信息 ip addr
服务器当前ip: 192.168.0.106, 网卡: enp0s3
5.修改配置文件
>vim /etc/sysconfig/network-scripts/ifcfg-enp0s3
TYPE="Ethernet"
BOOTPROTO="static" #静态方式
NM_CONTROLLED="no" #不使用网络管理器
DEFROUTE="yes"
IPV4_FAILURE_FATAL="no"
IPV6INIT="yes"
IPV6_AUTOCONF="yes"
IPV6_DEFROUTE="yes"
IPV6_FAILURE_FATAL="no"
IPV6_ADDR_GEN_MODE="stable-privacy"
NAME="enp0s3"
UUID="2b4bcec5-6c11-411b-b7b5-177d6b1075b2"
DEVICE="enp0s3"
ONBOOT="yes"
IPADDR=192.168.0.110 #设置固定ip
NETMASK=255.255.255.0 #子网掩码为物理机子网掩码(subnet mask)
GATEWAY=192.168.0.1 #设置网关为物理机网关(gateway)
6.重启网卡
>service network restart
7.添加DNS服务器
>vim /etc/resolv.conf
# Generated by NetworkManager
search localdomain
nameserver 114.114.114.114 #114DNS
nameserver 114.114.114.115
8.验证ip
>ip addr
